Four members of the Georgia Tech Research Institute’s (GTRI) faculty have been honored by the University System of Georgia's (USG) Board of Regents with 2024 Regents’ Researcher designation. These accolades recognize the recipients’ outstanding contributions and excellence in education, research, and innovation. 
GTRI research faculty named as Regents’ Researcher are:

• Gregory Showman, Principal Research Engineer in SEAL and GTRI Fellow. His existing Regents’ Researcher designation was reaffirmed this year by USG.
• Jeffrey Sitterle, Chief Innovation Officer, Information and Cyber Sciences Directorate.
• Jie Xu, Principal Research Scientist in ATAS.
• David Zurn, Principal Research Engineer in ELSYS.

Each year, GTRI may nominate two research faculty members for Regents' Researcher. The college deans at the Georgia Institute of Technology (Georgia Tech) may nominate two academic faculty members for the Regents' Professor title and one research faculty member for the Regents' Researcher title. 
The GTRI researchers are among 19 members of the Georgia Tech community who received USG Regents honors. 

The titles are awarded upon approval of the USG chancellor and its Committee on Academic Affairs only with unanimous recommendation of the Institute Regents Professor and Researcher Selection Committee, the Georgia Tech president, the executive vice president for Research, and the provost and executive vice president for Academic Affairs.
